T 0 all whom it may concern Be it lmou n tha t I', \V A I Jr :1: l melrr, a citizen of the Unitcd 'States'; residing in New' York, in the'coiintyofNe'w York and State of New Yorli,' hay e' im eiit'edcertaiii new and useful Imbrmfemeniis in Combined ly'pe-lvriting and 'Cor'npiitind Machines, of which the following is ja' specification: i

This invention relates to the mechanism which produces the ste ifbiistfep denominationa l movement between the inasterr wlieel and the connjntin g'i \i heels of abornbi ned typewriting and computing machinl'f'and more particularly to 'niean's' for automati- Cally connecti and disconnecting" the trave ling member of the computing iiiech afnisi'n (ivhether be 'tlie inaster;iil eel or the gang of computing:wheels); with the main carriage of the typewriter, asis n'c es} sary for theoperation of cross addinga'rid for other purposes.

In the preferred ferm. of the invention, the master-Wheel is the traieling member: of the computing mechanism and it is conn'ected by a lever to a'latch or hook; 'a connection of this general,kindheiiigdisclosd iii certain ofmy pending United 'Stat'e s a'p plications The liook' is iempl oysed tdooiinect the paper carriage of tlie typewrit'er to the traveling master-Wheel; and'to auto.- ma tically effect (ilisconn ection therefromaiid reconnection thereto. i

One of. the principal features of the pres,- ent improvements is to simplify the constrnction and operation of the machine; and tothis end 'I employ theusuaicolumii-stoi) rack of a tabnlat'ing" typewriter in connection with the tra 'eling member of the coinputing device; and it will be understood that, so far as this feature of the invention is concerned, it is iinmaterial-fii'hether the movable member of. the computing device consists of themaster-Wheel or of the gang of computing wheels.

In said column stop rack Linsert blades or i lernbers in" :)os ition tobe engaged by saidhook; and these members may besuhstantially in the form of ordinary column stops, and may; desired, perform the usual function of thecolumn stop, in'addition to the function of serring; to connect the P pe arri g ii lx i ew -li g; m b ofthe computing mechanism 'so' that the operater I setting, the: feoluniii stop to 'plosi't o l l for writing figures' iri the groper column on the page; may, 'by 1tlie s'ame act, position the column sto for connecting. the @Qmp i mecl aiiisn fto the/carriage to add the iiiini berjs iiiritterji' in"s'uch"colu1nn. As :set ortli in 'n eiidihg' Uiiited Stats applicatio i s the master-wheel and the ring of adding 'ivhfee'ls are cbnst'antly opera ire, i that 'iifhen l 1iu1neral"lie of the? ty e u rite r isdepresjsed, any hart of the hn'e Qf '1*iting,' said'master ifhel'will'tiirn', a'rid e f i5b 2 i m ii l 1 d d the cbi fs p i ei gjwh li e. the cbmpntin'g Hie chan'is'iri; the 0:115 function 'of 'the 'h66k and oflsaid blade or member being tdbh writer carr lage v Fifi i'is la' sectional plan of that portion 'of the dom'pu't'ing niech'anisni which is ii rolyed in I the present invention.

In the Underwood machine numeral keys 1 depress leiter's 2 toribrate'bellcrank's'3, and swingjtype' bars 4 up to strike rear- War'dly' against the front' side of a plat-en 5. Said blateri is mounted on a car'riaget,

running on tracks 7, 8, and is driven bya spring barrel 9, and also has a rack 10 meshing with a pinion 11 connected to" an escapement wheel 12, the escapement dogs, which are operated at every key stroke, be-

ing omitted; The raekclO is'hungonarms 13, so that it may be lifted from the pinion 11 to release the carriage. Tabulator keys 14 are mounted upon leveis-15, which,"attheir rear ends, raise the stop rods 16, having decimal st ops .l7 at their upper ends. These stops may c06p-' erate ,with interchangeably adjustable column t sj i igy of eo' tdi r i s; said columnlfstops beingins'erted, as re; quired, notches 19,20, formedinthe top and bpttom oiija'ta l 21, which i fixed to t arr s? 6 .s A

' Eael Id eimal stop-rod has a shoulder 22 Co6pei'ating: with a, universal bar'23, which rocks about a pivot 24,;a'nd has an arm 25, which draws down a. link.26. and vibrates a lever 27, the latterfulcrumedat 27 f ,and carrying a, roll ,2fZ ".to run upon the'under side 1 of the l rajck bar, 10, and lift the latterfrom the .eseapemeiit pinion 11, when: ever a key 14 is 'depressed. Asjso' 'far de scribed in detail, the partslarefin'coinnion useuon said Underwood:tyfp'ewriting' ma,- jchinef I IR If The computing 1 :echajni's'in includes a driv e shaft 28, havinggj a bevel," pinion 29 meshing with afpinion I30 upon a' square shaft 31', the latter being splined to a master-wheel 32, which. moves alongthe :shaft and has spurs or teethfiig toengage Janinternal set .of teeth.34.'formed-upon a gang of computing wheels 35, the latter, mounted in a casing 36 and also having, exterior teeth. 37 to mesh with gears 38, the latter having number wheels '39 The masterwheel 32 is swiveled in a, traveling hollow mandrel or arbor .40, within which the master-wheel shaft 31 may project, thes'wiveljoint being shown at 41, andpermitting the master-wheel 82 to be rotated by the shaft 31, while said master-wheel is caused to travel in axial direction by the mandrel or arbor40..- v v The mechanism so far described in detail forms no part of the present invention, and the drive shaft 28 may be driven and'controlled either directly by-the numeral keys 1 or in any other suitable manner, as for instance in the manner set forth in my pending application No. 569,502, filed June;29, 1910. Since the driving means for said shaft form no part of the present invention, it is deemed unnecessary to illustrate the same. The shaft, it will be understood, is rotated automatically upon the depression of any of the numeral keys 1, the extent of rotation depending upon which key is depressed.

the lever is slotted-at 44 to engage a pin 45 projecting from the carriage which carries the mandrel 4O said carriage comprising atube 46 sliding upon a fixed rod 47, and also anarm 48, slidin upon a fixedhori- .z ontal rod 49.; the man rel 40 being secured to the forward end'of the arm 48 by means of a set-screw 5Q. The movement, of the mandrel AOi Of course only sufficient to enable the master-wheel 32' to travel the length'of the gang of computing wheels 35, one of which is provided for each number Wheel "39. The rod47 cooperates with two fii nilarrods or'studs 47-'and 47, all projecting from a framework plate or bracket 479,,to carry a small iplate, 47 which also supports the end of rod 49. It will be seen that wa d 47",, Fig. 1, carry the casing 36. rear end, the lever 42 has a slot 51 to engage a pin projecting down froma slide, 53, the latter. carrying the stem 54 .of;'a'. h ook55, adapted to engage lugs 56 formed ,uponsaid stops l8 or upon blades .57 whiehare'forked to fit intovth'e double rack19,, 20,-f0r eonnecting the paper earriage, 6v:to ,the,master-wheel 32 to cause the latter to travelstep by-step with the paper carriage. I

-The; slide 53works in a tubular guide or housing 58, which. is slotted on its under side at 59 to permitthe pin 52 to pass down to the lever 42. The stem 54 of the hook 55 passes through a longitudinal perforation in theslid'e 53, and is adjustably secured to thelatterbyset screws 60, Fig. 2. This permits/slight longitudinal adjustment of the hookrin order to enable the'master-wheel 32to be adjusted properly relatively to the computing wheels 35 while the hook is engaged by oneiofthe lugs 56. The rack 21 has at 60 the usual provision for longitudinal adjustment. The slide 53 has a feather 61, to fit into the slot 59, to prevent the slide and the hook from turning inthe tube.

Thehook has a noteh 62 to enable it to engage any of the lugs 56. The hook normally springs up to engage the adjacent lug. Eorthis purpose the hook may be made resilient or flexible, and a compression spring 63 may be employed to aid or cause the upward movement of the hook; said spring housed in a boss 64, and confined by a screw 65, and pressing a plunger 66 up against a straight portion of the under side of the hook, thus holding the latter up while permitting it to move freely endwise. The boss 64 is formed on a bushing 67, which is vertically slotted at 68 to igeeegees nomination, cam '69"f0r ned4 on the hook 55 engages a projection 70' fixed uponthe framework of the machine,' "and is thereby forced downwardly, to withdrawj'the hook 555 from that lug 56- with which 'itll afi iiell in engagement." 'As sooiiasthe hookis'r eleased, a i'etu'rr'iin sprin 71*- connected to h 1 h v the lever 42f swings the latter in the oppositedire'etiong' cari-ying'thel master w'heeh 32 backwardlvor to the rightaat Fig-L 4; that'is, toward the computing'wheel' 35 of 'h-ighest denomination; this movement: continiiing until the hook 55- engages thesucceeding 1ug- 56; said hook being pressedj up toengage said lu'gby means of-the spring-63,

At Fig. 8, the lug 56 is shown in the form of acontinuation or extension of-j the lower of the two prongsseen at Fig; 9, and-hence this blade 57 maybe used for both tabulating purposes, in connection with the keysl, and for-connecting the master-wheel '32 'to the papercarriage 6'; at=the-propenpoint in the travel of the l'atten to-enable the number written in the selected column to be added upon-the-correspondingoomputingwheels35.
